Poisonous and harmful and flammable gas detection alarm system

Abstract

The invention discloses a poisonous and harmful and flammable gas detection alarm system comprising a monitoring center computer and a plurality of poisonous and harmful and flammable gas detection alarm terminals connected with the monitoring center computer through RS-485 bus. Each poisonous and harmful and flammable gas detection alarm terminal comprises a gas alarm controller. The input end of the gas alarm controller is connected with flammable gas detectors and poisonous and harmful gas detectors. The output end of the gas alarm controller is connected with a first explosion-proof electric actuator, a second explosion-proof electric actuator and a third explosion-proof electric actuator. The first explosion-proof electric actuator is connected with an explosion-proof sound-light alarm; the second explosion-proof electric actuator is connected with a cutting valve; and the third explosion-proof electric actuator is connected with an explosion-proof blower fan. The poisonous and harmful and flammable gas detection alarm system is simple in structure, reasonable in design, high in sensitivity, stable and reliable in performance, long in service life, good in performance, wide in application range, good in usage effect, and convenient to use and popularize.

Description

technical field [0001] The invention relates to the field of intelligent security technology, in particular to a toxic, harmful and combustible gas detection and alarm system. Background technique [0002] With the development of modernization in our country, the construction of various types of industrial buildings is developing rapidly. During the construction process, people pay more and more attention to the prevention of fire, especially. In recent years, the national fire protection law has promulgated and implemented relevant laws and regulations, and the prevention of fire in engineering construction has been raised to the height of law. The principle of "prevention first, combination of prevention and fire prevention" that is required for the fire protection system indicates that the automatic fire alarm system will play a more important role. The automatic fire alarm system is to allow people to detect fires early and take effective measures in time to control and...

AI Technical Summary

Problems solved by technology

The automatic fire alarm system is to allow people to detect fires early and take effective measures in time to control and extinguish fires. In industrial sites in petroleum, chemical, steel, metallurgy and other industries, natural gas and liquefied petroleum gas are easily generated during the production process. , coal gas and other combustible gases, produce ammonia, carbon monoxide, sulfur dioxide, hydrogen chloride and other toxic and harmful gases, which seriously affect the health of personnel in industrial production, and the secondary disaster of gas in the event of a fire also causes great losses to industrial production and society
